William A. Barry said this quote

We remain free, however, to listen to God's communication or not to listen, and free to respond or not to respond to what we hear. When we speak of contemplative prayer, we are speaking at the same time of awareness of this communication by God and of a willingness to listen and respond. Conscious relationship begins when I choose to listen to or to look at what the other is doing. After I have made this choice, I then freely decide whether to respond or not. Thus, by contemplative prayer we mean the conscious willingness and desire to look at and listen to God as God wishes to be for me and to respond. I may accept or reject God's initiative. in either case I have responded. When this process occurs, the person has the 'foodstuff' for beginning spiritual direction. (p. 34
